FAUCET.

To all whom fit may concern.'

Be it known that I, CHARLES A. TILLY, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful Improvements in Faucets, of which the followingis a specification.

This invention relates to faucets so designed as to dispense withrubber, leather or other packings around the valve stem.

The invention has for one of its objects to improve and simplify theconstruction of devices of this character so as to be comparativelysimple and inexpensive to manufacture, and reliable and efficient inuse.

Another object of the invent-ion is the provision of a. faucet in whichthe valve is provided with a taper against which the cap nut is adaptedto bear, the nut being formed with a conical seat whereby a watertightjoint is provided.

With these objects in view and others, as will appear as the descriptionproceeds, the invention comprises the various novel features ofconstruction and arrangement of parts which will be more fully describedhereinafter and set forth with particularity in the claim appendedhereto.

In the accompanying drawing, which illustrates one embodiment of theinvention, Figure l is a vertical section of the valve. Fig. 2 is a planview thereof. Fig. 3 is a vertical section of the cap nut. Fig. 4 is aplan View thereof. Fig. 5 is a vertical section of the faucet. Fig. 6 isa fragmentary sectional view of the casing or body of the faucet. Fig. 7is a side elevation of the faucet.

Similar reference characters are employed to designate correspondingparts throughout the views.

Referring` to the drawing, A1 designates the valve which is tapered andground to t a correspondingly-shaped seat B1 of the casing or body B ofthe faucet and above the downwardly tapered portion of the valve is anupwardly-tapering portion A2 which is gradually ground to t a conicalseat C1 of the cap nut C, said seat being also carefully Specificationof Letters Patent.

is provided with a removable handle D. The A valve has a port A3 whichis adapted to register with the passages B2' and B4 of the faucet. Thevalve casing B is formed with a tubular neck portion B2 which isinternally threaded to receive the tubular portion C1 of the nut C2, thesaid tubular portion being externally threaded to screw into the neckB2. The seat Cl is provided in the tubular portion of the cap nut sothat when the cap nut is screwed home, the said seat will tightly engagethe taper A2 of the valve. On the cap nut is a cylindrical flange C3which fits over and around the neck B2 of the casing B.

Having thus described the invention, what I claim is A faucet comprisinga casing having inlet and outlet passages arranged in alinement andprovided with an integrally formed tapering valve seat extending acrossthe passages at a point between them, a tubular neck extension disposedin line with the seat and having its bore adjacent the inlet and outletpassages tapered, a ported plug valve having a tapering body adapted totightly engage the wall provided by the tapering valve seat and thetapering portion of the neck, a stem connected with the said taperedportion, a cap nut having a tubular member engaging in the said neckextension and also provided with a cylindrical flange arrangedconcentric around said tubular member and spaced therefrom for engagingthe outside of the neck extension, the central tubular member of the capnut having the lower portion of its bore tapered and adapted to bearupon the upper portion of the tapered valve to form a water-tight joint,and means for revolving the ported plug valve.

In testimony whereof I afx my signature in presence of two witnesses.

CHARLES A. TILLY.
